Answer:
a. Heterozygous individuals may pass on their copy of the disease-causing allele to offspring.
Explanation:
Tay-Sachs, which is a recessive lethal disease ---- Let say the recessive lethal diseases is s
∴ it only results when an individual posses two copies of the diseases-causing allele i.e two copies of the disease will be ss.
Now, when two hetrozygous individuals crossed , it is obvious that each can pass on their copy of the disease-causing allele to the offspring.
Let show an illustration for the above statement.
Let the heterozygous individual be Ts, if Ts cross with another Ts;
we will have:
Ts × Ts
T s
T TT Ts
s Ts ss
the offspring are TT,Ts,Ts,ss
We can now see how the Heterozygous individuals pass on their copy of the disease-causing allele to the offspring (Ts).
One difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together (option C).
<h3>What are cancer cells?</h3>
Cancer is a disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
When normal cells become cancerous, they lose the ability to regulate cell division, hence, they continue to divide excessively.
Normal cells are characterized by their ability to regulate cell division during the cell cycle.
Therefore, one difference between cancer cells and normal cells is that cancer cells continue to divide even when they are tightly packed together.
